Wavefront Adapter for Istio is an adapter for Istio to expose Istio metrics to Wavefront. It is a lightweight tool written in Go. It supports Istio v1.4+ and Kubernetes v1.15+.
Overview of Wavefront Adapter for Istio
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/wavefront-adapter-for-istioBitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.
This will deploy a Wavefront Adapter for Istio Deployment in a Kubernetes cluster using the Helm package manager.
Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.
- Kubernetes 1.19+
- Helm 3.2.0+
- Istio v1.4, v1.5 and v1.6 with
Mixersupport
In order to enable the Mixer in Istio versions starting from v1.5, execute the following commands:
istioctl manifest apply --set values.prometheus.enabled=true --set values.telemetry.v1.enabled=true --set values.telemetry.v2.enabled=false --set components.citadel.enabled=true --set components.telemetry.enabled=trueistioctl install --set values.prometheus.enabled=true --set values.telemetry.v1.enabled=true --set values.telemetry.v2.enabled=false --set components.citadel.enabled=true --set components.telemetry.enabled=trueTo install the chart with the release name my-release:
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/wavefront-adapter-for-istioThese commands deploy wavefront-adapter-for-istio on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.
Tip: List all releases using
helm list
To uninstall/delete the my-release helm release:
$ helm uninstall my-releaseThe command removes all the Kubernetes components associated with the chart and deletes the release.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,
$ helm install my-release \
--set livenessProbe.successThreshold=5 \
bitnami/wavefront-adapter-for-istioThe above command sets the livenessProbe.successThreshold to 5.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
$ helm install my-release -f values.yaml bitnami/wavefront-adapter-for-istioIt is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
The Wavefront Adapter for Istio chart needs to be connected to a Wavefront instance. This can be done in three different ways:
-
Deploying the Wavefront subchart, using only the Wavefront Proxy component (default behavior): This is done by setting
wavefront.enabled=trueandwavefront.proxy.enabled=true, but leaving theexternalProxy.hostvalue unset. We recommend disabling the rest of the Wavefront sub-chart resources as they would not be used by the Prometheus Storage Adapter. You also need to configure the Wavefront SaaS URL and token using thewavefont.wavefront.urlandwavefront.wavefront.tokenparameters. -
Using an external Wavefront Proxy instance: This is done by setting the
externalProxy.hostandexternalProxy.portvalues. In this case, you should set thewavefront.enabledvalue tofalse. You also need to configure the Wavefront SaaS URL and token using thewavefront.wavefront.urlandwavefront.wavefront.tokenparameters. -
Use direct ingestion without a Wavefront Proxy instance. This is done by not setting the
externalProxyvalues and setting thewavefront.enabledvalue to false.
Refer to the chart documentation for more detailed configuration examples.
